Victor embodies all the wrongs a petty ganger might commit. He is a psychopath, reveling in pain and bloodshed. Since usually he can't hurt humans with impunity, he tortures iguanas he catches around Junktown. He also had a tendency to stare at people in an unsettling way and stalk them.[1]
Stupid characters with less than 4 Intelligence will cause Victor to laugh himself to death (hit for 200 hit points a few moments after the player talks to him).
